Reset button

Press the SW1 button on the EVB to reset the MAYA-W1 module. When pressed, SW1 asserts the

PDn

pin of the MAYA-W1 module to enter power down mode, while keeping the supply rails enabled.

The module is automatically reset when it exits the power down mode, which means that the firmware
must be downloaded again.
